Failed to read ppd file but printer is working well

I have an HP printer. It works well. But on runninghp-checkit shows

warning: Failed to read /etc/cups/ppd/DeskJet-5820-series.ppd ppd file

Do I have to worry about this? What do I do to fix it?

Basically, you have the same problem as Printer stack on processing - failed to read ppd file

You just need to change the permissions of read / write of the file

$ sudo chmod 644 /etc/cups/ppd/HP-LaserJet-Pro-MFP-m125nw.ppd

I just followed these 2 answersanswer1, answer2

Don't worry so much and give others a headache.
